Wuhuan

The Wuhuan were a Mongolic nomadic people who inhabited northern China. The Wuhuan and Xianbei both originated with the Donghu tribe, which was destroyed by the Xiongnu in 209 BC, and the Wuhuan settled around the Liaodong Peninsula. In 121 BC, Han dynasty general Huo Qubing settled the Wuhuan in Shanggu, Youyang, Youbeiping, Liaoxi, and Liaodong), and the Wuhuan made annual visits to the Han court. This cooperation ended in the 190s, when the Wuhuan took advantage of the chaos in China to invade and plunder the north. In 207, the Han general Cao Cao marched north and defeated the Wuhuan at the Battle of White Wolf Mountain, and many Wuhuan horsemen joined ranks with him after the battle. By the 4th century, they had largely been displaced by the Xianbei, and the Khitans absorbed the remaining Wuhuan in the 10th century.
